You already have the answer but the technical name is "wear indicator"

When it gets to a lower thickness you get that classic high pitch squeal, which gives you enough time to replace it before rotor damage is done.

If you don't have it and are totally inept (which no one here is) the only squeal would be either an aggressive pad when cold or way later in it's life something rubbing right against the rotor like the rivets on the pad or the like. At that point you've probably damaged the rotor.

If you're smart enough to replace the pads yourself like everyone in this thread is, you probably don't need the wear indicator because you can feel the pads loosing effectiveness and know when to check the pad wear
